Section 1
Room Requirements
General Information
Forte cameras consist of a Gantry, a Collimator Storage Unit (for holding up to four pairs of heavy collimators), a Patient Table, an Acquisition Terminal and a Processing Workstation (also called a PegBlade).
The Gantry is a stationary “ring-shaped” device which Philips anchors to the floor. The Gantry supports two Detectors from which the system collects images of the patient. See illustration on page 1-3.
The Patient Table is on wheels, but, unless moved out of the way to accommodate gurney-bound patients, remains in the same location. As shown on page 1-3, the Patient Table includes a moveable Pallet which translates the patient in and out of the Gantry Ring.
For Emission Computed Tomography (ECT) studies, the two Detectors rotate around a patient lying on the Patient Table in the center of the Gantry Ring.
For Total Body Studies, the two detectors remain above and below the patient. The Patient Table moves the Pallet (and patient) in and out of the Gantry Ring.
To image patients on gurneys, operators move the Patient Table out of the way and place the gurney under the camera but perpendicular to the normal table position.
Forte Models
There are two models of Forte Cameras:
•Forte with Atlas Electronics Rack (Forte Atlas) - manufactured before November 2000 which requires an additional electronic rack in the room.
•Forte with Power Pack (Forte Power Pack) - manufactured after December 2000 which have a slightly larger compartment behind the Gantry. That compartment contains the electronic components formerly contained in the separate Atlas Electronics Rack.
Collimator Storage Unit
The Collimator Storage Unit may contain up to eight collimators (four pairs). Collimators are 21" x 26" (53cm x 66cm) sheets of lead of various thicknesses. Collimators weigh between 110 and 235 lbs (50 and 107 kg).
Prior to performing clinical studies, the operator must transfer a pair of collimators from the Collimator Storage Unit to the pair of Detectors on the Gantry. To do
1-1
Section 1: Room Requirements
collimator transfers, the Collimator Storage Unit is on wheels. It moves between “park” and “exchange” positions along an arc around the corner of the Gantry.
Left and Right Configurations
Philips can install the Collimator Storage Unit on either the left or right side of the Gantry.
Philips recommends installing the Collimator Storage Unit on the side of the Gantry where the patient enters the room. This allows operators to assist the patient getting on or off the table and also reach controls on the Display Panel on top of the Collimator Storage Unit.
The operator will also want the Acquisition Terminal on the same side of the Patient Table as the Collimator Storage Unit. Other configurations will require the operator to frequently walk around the Patient Table.
Section 2 contains illustrations of rooms with left and right Collimator Storage Units. Those illustrations show recommended directions of patient access and locations of the Acquisition Terminal.
Air Conditioning Requirements
The Forte camera has the following heat loads:

||
The camera room HVAC system must maintain the temperature between 60°- 75° F (16° - 24° C) with less than 10° F (5° C) variation per hour. Humidity must be between 20% - 75%. These requirements are 24 hours per day, 7 days per week.
Floor Levelness Requirements
The floor under the four Patient Table wheels must be at the same level (±0.25" or 6 mm) as the floor under the Gantry .
The floor under the Collimator Storage Unit rails must be at the same level (±0.125" or 3 mm) as the floor under the Gantry.
If floors do not meet these requirements, the customer will need to correct the floor levelness problem before Philips can begin an installation. To avoid trip hazards near the Gantry, Collimator Storage Unit and Patient Table, any floor correction measures (such as grout) must taper down to the existing floor away from the Gantry, Collimator Storage Unit and Patient Table. See illustration on page 6-8.

Room size requirements are slightly different for Forte Power Pack and Forte Atlas cameras. Room layout drawings appear in Section 2.
Forte Power Pack Cameras
For Forte Power Pack Cameras, the room sizes requirements differ slightly depending on whether the Collimator Storage Unit is on the left or right side of the Gantry.
Although larger rooms are preferable, acceptably small rooms for Forte Power Pack cameras may have these dimensions:

Important: Unless the floor is a ground-level, reinforced 3,000 psi (211 kg/cm2), 4.5" thick, poured on grade concrete slab, a licensed structural engineer must evaluate floor loading. To evaluate floor loading, a structural engineer will need the data in Sections 3 and 6 of this document. See Section 5 for shipping sizes or weights.

Vibration Specifications
Nuclear medicine cameras do not have floor vibration specifications. This is because
(1) image collection durations are long (10 - 300 seconds, or more) and floor vibration durations are much smaller, (2) vibrations are typically sinusoidal and, therefore, tend to cancel out, and (3) the patient table and detector/gantry assemblies are both floor mounted and, therefore, vibrate together.
________
1In Forte Atlas cameras, the Atlas Electronics Rack provides power to the Gantry, Collimator Storage Unit, Patient Table and Acquisition Terminal.
In Forte Power Pack cameras, the Gantry provides power to the Collimator Storage Unit, Patient Table and Acquisition Terminal.
Forte Atlas and Forte Power Pack cameras have the same power requirements.
